A dealer purchases 12 apples for rs 10 and sells 10 apples for rs 12, what was his gain percentage?

Since,12 apples purchased for RS. 10

So, 1 apple purchased for RS. 10÷12

Hence, c.p of 1 apple=5/6=0.833

Again,

Since,10 apples sold for RS. 12

So, 1 apple sold for RS. 12÷10

Hence, sp of 1 apple=6/5=1.2

Since, sp>cp

Hence, gain=1.2–0.833=0.367

And gain%=(gain/cp)×100=(0.367÷0.833)×100=
